Abstract
The specific heaf Cp (cal·g-1·deg-1) of the brine (sp. gr. d254=1.1258) produced by electrodialysis of sea water with ion exchange membranes and its six kinds of concentrate were determined at 30.0, 50.0 and 70.0°C.
The relation between the specific gravity d254(=1.126-1.204) and the specific heat Cp of the solutions up to the saturation point of sodium chloride was analyzed by statistical procedure of quality control, and thus there was found a very significant regressive relation. The following were the regression line at each temperature and the estimated error E from each line:
Cp30=-0.849d+1.785, E=0.001
Cp50=-0.812d+1.735, E=0.002
Cp70=-0.809d+1.722, E=0.003
